Polymaker is hosting a 3D Printed Hook Tournament.
We invited the 3D printing community to show off their engineering skills and design the strongest hook!
During this single-elimination tournament, hooks are facing each other in a tensile strength contest until one of them breaks or let go. From the qualifiers to the final, only one will survive! However, the top 3 hooks will be rewarded with prizes.

Its insane how well this project is going
Yep 👍🙏
Holy sh** Michael Devitt made an s-hook that withstood 1200lbs!!!!! That is worthy of an award sir. Great job!
Even more impressive is he came back from the dead. He was eliminated in Round 3! :-)
Loving the new format, and the music! 🤣 Epic, especially the one that snapped the fixture but went on to win.
I literally stopped breathing during the Hookinator 3Million battle, thats intense ! haha
That was a great one. Both were being pushed hard.
@@NotWorkingAtAll 880kg! thats crazy, also the black got a nice RIP music haha
The force on that last loop broke the support for the little hook, so it won with just 3 of the loops. I bet Hookinator is one of the hooks that beat the testing machine with more than 10kN
@@santiagoblandon3022 At least they put something for the end to hook onto although it did break but it held on just enough. Looks like they printed the extra bit, probably from PA6-CF, need to make it stronger for next time, looks like the thin bits broke. I think we're up against each other in the next round so, good luck and may the best hook win :).
@@Bordpie Thank you! Good luck to you too :D

Polymaker! if you're reading, please include the strain vs stress curves of your materials in the Technical Datasheets! 🙏
Is there any chance my hook can compete as a wildcard? Plasmashears' hook was used in place of mine in my round, Round 2 Part 1/2
Not complaining but the fixture for Sendit hook seems slightly unfair. Great video though!
Unique solution, yes. But not "unfair". Most of the remaining hooks can use the U-bolts and still be properly loaded. #Sendit and Hookinator rely on the specific geometry of the metal S hook that was very clearly specified in the rules. For both, they utilize the crossing piece of the "S" to support the load of the hook. So I would argue it's only "fair" for Polymaker to come up with a solution that loads the hook similar to the way the S-hooks would have. And it looks like they are doing just that.
@@twinturbostang I agree that the custom fixture is fine based on the fact that the hook relies on the S shape, although based on the specific loading with that hook, the larger fixtures may help resist the bending loads somewhat. Since with the metal hooks, the round profile can twist against the surface more easily, while with the more square profile of that fixture it would be a bit more difficult. Since they are using welded metal hooks anyway this is a non issue. The same with my hook but they didn't make the extra bit strong enough apparently so they went to welded hooks as well. Possibly also for consistency.
@@twinturbostang That's a fair point. I guess what I'm getting at is that I think next time they should have more clearly defined categories. Because obviously an s-hook will never beat a spiral design etc. It would be interesting to see which is the strongest in each category.
@@jonathanbarger2493 In the begining nobody even knew there were such things as spiral hooks... It was "bring the best idea you have"
But now that they're recording the loads at which hooks break, I believe they will sort it according to that and there one can see which was the best of each "category"
@@jonathanbarger2493 They wanted to get unique and creative designs. I'd say they sure got them! But I think what nobody had predicted was how STRONG 50 grams of plastic hook could be! They ran into issues when the hooks started bending/breaking the metal S hooks and had to come up with alternative solutions that still loaded the 3D printed hooks as they were designed. With more restrictions in the contest rules, this probably could have been avoided. Like limit the weight to 25 grams instead. Or specify a minimum distance that the metal S hooks could be placed to each other. That would have eliminated my design immediately. Anyway, they've said they might run another contest. If so, I'm sure there will be more rules in place. My guess is another contest like this is going to be even harder. I think everybody has learned quite a lot in terms of what works and what doesn't.
Didn't they say the final is on the 8th December? That means they have to get through all the rounds before then or will it be in one big video?
I asked them on FB. They said they reached the limit of their test rig. They couldn't break the hooks in the semi-final round!! So they're working on another solution. They said the final video will be next Thursday. But I'm assuming that's if they figure out how to break the hooks in time. :-)
@@twinturbostang Just Wow.
The fixtures for #Sendit_Hook were impresive! what are those made of?
I was wondering the same, my guess is that they printed the fixture using their PA6-CF
I think you're right! I'm dying to print with that material, but 3Kg are hard to justify =/
@@santiagoblandon3022 Yes, that was their CF material. Apparently that didn't even hold and they went with a welded steel hook.
WOW
